|A New Active Snubber Circuit for PFC Converter|
In this paper, a new active snubber circuit is developed for PFC converter. This active snubber circuit provides zero voltage transition (ZVT) turn on and zero current transition (ZCT) turn off for the main switch without any extra current or voltage stresses. Auxiliary switch turns on and off with zero current switching (ZCS) without voltage stress. Although there is a current stress on the auxiliary switch, it is decreased by diverting it to the output side with coupling inductance...
